Playtester: Alt shortcuts (peek top X library) don't work on MacOS

{"ops":[{"insert":"Hey, i'm playtesting an Aminatou precon on Spelltable and it surveils 2 each turn. \nI've noticed there's a shortcut (alt+1,2,3..x) to speed up peeking top X cards of the library, but it doesn't seem to work on MacOS, and I've tried Firefox and Chrome.\nCMD+S/F and other binds work fine.\nIt does work on Windows. I suspect there's a different key id used on MacOS for Alt, since Apple calls it an Option key. \n\nPlease take a look, surveilling with a mouse takes 3 clicks (library, peek, peek X), would love to do it quicker.\n"}]}
